Mandevilla plant named ‘Lannevada’

ABSTRACT

A new and distinct cultivar of  Mandevilla  plant named ‘Lannevada’, characterized by its trailing plant habit; moderately vigorous growth habit; glossy dark green-colored leaves; early flowering habit; and red-colored flowers.

Botanical designation: Mandevilla sanderi.

Cultivar denomination: ‘LANNEVADA’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofMandevilla plant, botanically known as Mandevilla sanderi andhereinafter referred to by the name ‘Lannevada’.

The new Mandevilla plant is a product of a planned breeding programconducted by the Inventor in Malause, France. The objective of thebreeding program is to create new trailing Mandevilla plants withred-colored flowers.

The new Mandevilla plant originated from a cross-pollination conductedby the Inventor in Malause, France on Sep. 22, 2006 of Mandevillasanderi ‘Sunmanderemi’, disclosed in U.S. Plant Pat. No. 16,449, as thefemale, or seed parent with a proprietary selection of Mandevillasanderi identified as code number 05-075-22, not patented, as the male,or pollen, parent. The new Mandevilla plant was discovered and selectedby the Inventor as a single flowering plant from within the progeny ofthe stated cross-pollination in a controlled greenhouse environment inMalause, France in May, 2008.

Asexual reproduction of the new Mandevilla plant by cuttings in acontrolled greenhouse environment in Malause, France, since May, 2010has shown that the unique features of this new Mandevilla plant arestable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Mandevilla have not been observed under all possibleenvironmental conditions and cultural practices. The phenotype may varysomewhat with variations in environmental conditions such as temperatureand light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Lannevada’. These characteristics incombination distinguish ‘Lannevada’ as a new and distinct Mandevillaplant:

-   -   1. Trailing plant habit.    -   2. Moderately vigorous growth habit.    -   3. Glossy dark green-colored leaves.    -   4. Early flowering habit.    -   5. Red-colored flowers.

Plants of the new Mandevilla can be compared to plants of the femaleparent, ‘Sunmanderemi’. Plants of the new Mandevilla differ primarilyfrom plants of ‘Sunmanderemi’ in the following characteristics:

-   -   1. Leaves of plants of the new Mandevilla are flatter and        thicker than leaves of plants of ‘Sunmanderemi’.    -   2. Plants of the new Mandevilla and ‘Sunmanderemi’ differ        slightly in flower color.    -   3. Flowers of plants of the new Mandevilla are resistant to sun        fading whereas flowers of plants of ‘Sunmanderemi’ are not        resistant to sun fading.

Plants of the new Mandevilla can be compared to plants of the maleparent selection. Plants of the new Mandevilla differ primarily fromplants of the male parent selection in the following characteristics:

-   -   1. Leaves of plants of the new Mandevilla are flatter and        thicker than leaves of plants of the male parent selection.    -   2. Plants of the new Mandevilla and the male parent selection        differ in flower color as plants of the male parent selection        have pink-colored flowers.    -   3. Flowers of plants of the new Mandevilla are resistant to sun        fading whereas flowers of plants of the male parent selection        are not resistant to sun fading.

Plants of the new Mandevilla can also be compared to plants ofMandevilla sanderi ‘Sherry’, not patented. In side-by-side comparisonsconducted in Malause, France, plants of the new Mandevilla differed fromplants ‘Sherry’ in the following characteristics:

-   -   1. Plants of the new Mandevilla were more trailing than and not        as upright as plants of ‘Sherry’.    -   2. Plants of the new Mandevilla were more vigorous than plants        of ‘Sherry’.    -   3. Plants of the new Mandevilla flowered two weeks earlier than        plants of ‘Sherry’.    -   4. Plants of the new Mandevilla had darker-colored flowers than        plants of ‘Sherry’.
